The results in 578 patients who underwent a saphenous vein bypass graft
operation (isolated SVBG) or a SVBG combined with other procedures
(combined SVBG) from 1969 through 1972 were analyzed. The operative
mortality rate was low (3 percent) for isolated SVBG but increased
considerably for combined SVBG. The late mortality rate was also low (4
percent) for isolated SVBG and also increased markedly for combined SVBG.
The operative mortality rate did not change in the group undergoing left
ventricular aneurysmectomy or mitral valve surgery for postinfarction
mitral insufficiency, whether or not SVBG was used; however, late results
were better in both groups when SVBG was performed. Among all groups,
patients with postinfarction mitral insufficiency or rheumatic mitral
incompetence associated with coronary artery disease had the poorest
outcome. Despite the operative and late deaths, patients undergoing SVBG
with aortic valve replacement showed excellent results in the group of
survivors.
